SX-1 Plasma Knee Guards - Black/Red/Cool Gray - 2XL
The Alpinestars SX-1 Plasma Knee Guards are designed to provide superior impact protection combined with excellent comfort for riders seeking reliable knee defense. Featuring a plasma knee protector embedded into a highly ventilated semi-rigid frame, these guards ensure durability while maintaining breathability during intense riding sessions. Constructed from USDA biobased viscoelastic material, the protector is flexible in all directions and effectively dissipates impact energy to minimize injury risk. The dual-density co-injected frame offers support and adaptability, conforming comfortably to various leg shapes while providing optimal protection. A scooped lower and upper extension made from soft polymeric blends prevent pressure points and skin discomfort, enhancing overall comfort during extended use. The strategic placement of rigid and flexible shells over the frames ensures the guards adapt seamlessly to different leg circumferences, providing a secure fit. The Patella System delivers full coverage of the knee cup regardless of extension degree, with a rigid outer shell that guards against handlebar strikes. Constructed from lightweight, high-performance polymers, the upper and lower frames are engineered for flexibility, strength, and weight savings. Their integrated dual pivot hinge system mimics natural knee movement, maintaining proper positioning during activity. The perforated design enhances ventilation, keeping the knees cool in hot conditions, while the slim ergonomic profile ensures minimal bulk. The dual strap closure system with hook-and-loop fasteners and snap-fit buckles allows for quick, personalized adjustments, ensuring a secure and comfortable fit for riders of all sizes. Whether for motocross, trail riding, or other high-impact activities, these knee guards deliver reliable protection, comfort, and mobility for demanding riders.
